Why High voltage test transformer causes short circuit?
A, the system uses an inflatable(SF6)Free PD test transformer.
It is difficult to make other test transformers without partial discharge.
HZGPNYT 3KVA/5KV power frequency withstand voltage test transformer I.
Inflatable high-voltage test transformers maintenance methods[Mar 21, 2019].
The maintenance methods of common inflatable high-voltage test transformers are as follows.
When there are many equipments and the test transformer has a small capacity, the test can be carried out in batches.
Dry test transformer completely changed the old-fashioned test transformer stupid, large, heavy backward conditions, and can be installed in supporting the production of high-pressure silicon stack can provide DC high-voltage test power, with control box(Taiwan), automatic protection micro-security Table, ball gap and other ancillary equipment, especially for on-site testing, so heavy work becomes convenient, fast, easy and flexible, greatly improved efficiency.
In these cases, it is necessary to have a test transformer without discharge.
Oil-immersed test transformer with small size, light weight, compact structure, full-featured, versatile and easy to use and so on.
It should also be noted whether the capacity of the test transformer is appropriate.
Inflatable high-voltage test transformer, mainly used in power system, industrial and mining enterprises, scientific research departments, etc.
The discharge in the test circuit,such as the discharge in the high voltage test transformer, can be detected by most discharge detectors.
Inflatable high-voltage test transformer, mainly used in power system, industrial and mining enterprises, scientific research departments, etc.
In addition to this, it is also necessary to consider whether the voltage on the low-voltage side of the test transformer can match the test conditions in the field.
One is an inflatable type partial discharge test transformer, and the other is an epoxy barrel oil-immersed type partial discharge test transformer.
Difference Between Oil-immersed test transformer And Dry Type test transformer.
The power supply used by the detector and the test transformer is connected to the low-voltage distribution network, and various high-frequency signals in the distribution network can directly cause interference.
As the table shows, please connect the control station with the test transformer, also please do not forget to connect with the floor line.
Connecting the control unit(it is the supplementary equipment of test transformer, detailed see the explaining book) with work frequency 220V(above 10KVA with 380V), adjusting 0-220V/380V voltage input to HZQ(YQ-JZ) test transformer primary winding through autotransformer.
HZT series control station is a complete set of equipment of high voltage test transformer, it and the test transformer carry out resistance pressure and leakage test. .
This set of test system consists of a test console,an inflatable no partial high voltage test transformer, a coupling capacitor and protection resistor, a set of isolation filter, the whole system has complete overvoltage, overcurrent protection and reliable, With the characteristics of small interference.
In the case of power detection test site use,the commonly used inflatable type partial discharge test transformer is small in size and light in weight, and it is convenient to move to the required position for on-site inspection and test. .

Power frequency without partial discharge test transformers should be precautions before AC withstand voltage test. .
In order to keep the pneumatic high-voltage test transformer in good condition, proper maintenance and maintenance is essential.
